Title
Is Sulfur Limiting Maize Grown on Eroded Midwestern U.S. Soils
John L. Kovar; D. L. Karlen 2010
Other claims from this paper (9)
- Intervention effect AMS showed a similar but nonsignificant upward trend in V5 plant dry weight.
- Intervention effect ATS showed a similar but nonsignificant upward trend in V5 plant dry weight.
- Intervention effect Whole-plant sulfur concentrations at V5 were generally higher than controls with all sulfur sources.
- Intervention effect Sulfur did not affect grain yield in 2006 and 2007.
- Intervention effect Sulfur did not affect harvest moisture content in 2006 and 2007.
- Intervention effect In 2008, SEF at 34 kg S/ha significantly increased grain yield by 0.76 Mg/ha.
- Observation SEF had the greatest sulfur agronomic efficiency in 2006, at 12.3 kg grain per kg S.
- Observation SEF had the greatest sulfur agronomic efficiency in 2008, at 22.5 kg grain per kg S.
- Recommendation The authors conclude sulfur may become limiting for maize, especially when stover is harvested for bioenergy.
